Statistics of low energy levels of a one-dimensional weakly localized Frenkel exciton: A numerical study
Statistics of low energy levels of a one-dimensional weakly localized Frenkel exciton: A numerical study
Numerical study of the one-dimensional Frenkel Hamiltonian with on-site randomness is carried out. We focus on the statistics of the energy levels near the lower exciton band edge, i.e., those determining optical response. We found that the distribution of the energy spacing between the states that are well localized at …
